Answer 2

To my knowledge, GMail only supports encrypted SMTP, and the error message is telling you that in a rather roundabout way. You'll need to configure Spring to use that instead of plaintext SMTP.

See this answer to a prior question which explains how to configure JavaMailSenderImpl to do this (I haven't tested it for myself, though).

You can see my blog post here at http://codersatwork.wordpress.com/2010/02/14/sending-email-using-gmail-smtp-server-and-spring-mail/ which explains how to use spring mail for sending email via gmail smtp server. Please let me know if this helps.
